Abstract
Improved yield and selectivity for the chloromethylation of 4-iso-octyl-1-methoxyl benzene were obtained under the combined catalysis of tetrabutylammonium bromide and zinc chloride.The conversion of the main reagent and the yield of the product were 100% and 95% respectively,under the following conditions:n(phenolic ether):n(formaldehyde):n(zinc chloride)=1:2:1.25,the reaction temperature 30~40℃.The product was characterized by IR and 1H NMR.
